Should Exposed Tree Roots Be Covered in Lynchburg, VA?

It's common to see tree roots begin appearing above the ground as trees mature. While some homeowners don't think much about them, others wonder if exposed roots should be covered with soil or mulch. The answer may surprise you. In many cases, covering exposed roots with soil can actually do more harm than good. Understanding why roots become exposed can help you protect the long-term health of your trees.

Why Do Tree Roots Become Exposed?

Most tree roots grow within the top 12 to 18 inches of soil because that's where they have the best access to oxygen and moisture.

Over time, erosion, heavy rain, foot traffic, and natural tree growth can expose portions of those roots. This is especially common with mature shade trees throughout Lynchburg.

Is It Bad for the Tree?

Not necessarily. Many healthy trees have exposed roots. However, exposed roots can become damaged by lawn mowers, string trimmers, construction equipment, or repeated foot traffic. Once roots are injured, insects and diseases may have an easier time entering the tree.

Should You Cover Exposed Roots With Dirt?

Usually, no. Adding several inches of soil over exposed roots can reduce the amount of oxygen reaching the root system and create excess moisture around the base of the tree. Instead, certified arborists often recommend applying a thin layer of organic mulch around the root zone rather than burying the roots under soil. Proper mulching helps conserve moisture while allowing roots to continue receiving oxygen.

Can Exposed Roots Damage My Yard?

Yes. Surface roots can make mowing more difficult, create trip hazards, and sometimes lift nearby sidewalks or walkways as the tree grows. If roots are causing problems near hardscapes, it's important not to cut large roots without professional guidance, as doing so can weaken the tree and reduce its stability.

Can I Cut the Roots?

In most situations, you shouldn't remove large surface roots yourself. Tree roots provide structural support and supply water and nutrients throughout the tree. Removing the wrong root can permanently damage or even destabilize an otherwise healthy tree.

If roots are interfering with sidewalks, driveways, or landscaping, a professional tree inspection can determine the safest solution.

How Can You Protect Exposed Roots?

Homeowners can help keep exposed roots healthy by:

• Applying a 2- to 3-inch layer of mulch around the tree
• Keeping lawn mowers and string trimmers away from exposed roots
• Avoiding heavy equipment over the root zone
• Watering deeply during extended dry periods
• Scheduling periodic tree health inspections

These simple steps can help mature trees remain healthy for many years.
